How can I recover my email domain reputation after a drop in open rates?

Summary

Recovering email domain reputation after a drop in open rates requires a holistic approach involving engagement optimization, list hygiene, robust authentication, proactive monitoring, and addressing the root cause of deliverability issues. Experts advise focusing on engaged subscribers, delivering valuable content, and segmenting lists to improve open rates and signal value to ISPs. Regular list cleaning, suppression of unengaged users, and prompt removal of hard bounces are crucial. Implementing SPF, DKIM, and DMARC, especially with a reject policy, safeguards sender reputation. Furthermore, actively monitor sender reputation via tools, respond to feedback loops, and adhere to best practices from mailbox providers like Gmail and Outlook. If new IPs are involved, gradually warm them up. Addressing the underlying causes, such as consent issues or irrelevant content, is essential for sustained improvement.

Key findings

  • Engagement First: Prioritize sending relevant, valuable content to engaged subscribers to demonstrate positive engagement signals to ISPs.
  • Hygiene is Paramount: Regularly clean your email lists by removing inactive subscribers, hard bounces, and unsubscribes to maintain a healthy list and sender reputation.
  • Authentication is Non-Negotiable: Implement and properly configure SPF, DKIM, and DMARC to authenticate your emails and prevent spoofing, protecting your sender reputation.
  • Monitoring is Key: Actively monitor your sender reputation using tools like Google Postmaster Tools and monitor blacklists for potential issues.
  • Address the Root Cause: Identify and fix the underlying causes of deliverability problems, such as poor consent practices, irrelevant content, or sudden volume increases.

  • Content Relevance: Ensure your email content is valuable and relevant to your subscribers to maintain engagement and avoid spam complaints.
  • Consent Practices: Only send emails to subscribers who have explicitly opted in to receive them, ensuring you have proper consent.
  • Gradual Warm-up: When using new IP addresses, gradually warm up your sending volume to establish a positive reputation with ISPs.
  • Feedback Loops: Actively monitor and respond to feedback loops to identify and address any issues raised by mailbox providers.
  • Blacklist Monitoring: Proactively monitor blacklists to detect if your domain or IP address has been listed, and take steps to resolve the issue immediately if found.
